Which shows one way to determine the factors of 12x3 – 2x2 18x – 3 by grouping?.

Answer:

7 times $8 = 56

Step-by-step explanation:

Question 1:

So, we are going to multiply 7 by $8.

If Brandie earns 8 dollars an hour, then we can multiply 8 by 7 to find out how much money Brandie earns in 7 hours.

Now multiply 8 by 7.

8 * 7 = 56

The independent variable is the hours. The hours can change, but this affects what the dependent result is.

The amount of money stays the same.

The dependent variable is the result, which is the total amount of money earned.

Hope this helps!

Given:

A race car game takes 6 points from a player each time the player hits a cone.

To find:

The integer which represents the change in total points if the player hits 10 cones.

Solution:

According to the given information,

1 hit = -6 points

Here, negative sign represents the reduction in points after hitting a cone.

If the player hits 10 cones.

(1 × 10) hit = (-6 × 10) points

10 hit = -60 points

So, the change in total points if the player hits 10 cones is -60.

Therefore, the required integer is -60.

Check the picture below, so the shaded area is really just the area of one quarter of a circle's area with a radius of 7, and a triangle whose base is 7 and height is 7, so let's simply sum both of them up.

[tex]\stackrel{\textit{\Large Areas}}{\stackrel{\textit{quarter of a circle}}{\cfrac{1}{4}(\pi)(7)^2}~~ + ~~\stackrel{triangle}{\cfrac{1}{2}(7)(7)}}\implies \cfrac{49\pi }{4}~~ + ~~\cfrac{49}{2}~~ \approx~~63.0[/tex]

The triangle is an equilateral triangle, therefore, Diego didn't draw the right triangle.

A triangle simply means a polygon that has three edges and vertices. It's a shape in geometry.

In this case, I don't agree with Diego's drawing as the triangle is an equilateral triangle and this means that each side is 60° and not 45° as illustrated.

Answer/Step-by-step explanation:

Given that a student wrote the following equation:

[tex] 2(n + 3) = 2n + 3 [/tex]

Looking at the expression on both sides, they don't seem equal. To be sure, use any value to represent "n" in the equation. Then, simply. If what you have on your left is equal to what you have in your right, then the equation is TRUE. If otherwise, it is FALSE.

Let n = 2

[tex] 2(n + 3) = 2n + 3 [/tex]

[tex] 2n + 6 = 2n + 3 [/tex]

Plug in the value of n

[tex] 2(2) + 6 = 2(2) + 3 [/tex]

[tex] 4 + 6 = 4 + 3 [/tex]

[tex] 10 = 7 [/tex]

This is not FALSE. 10 ≠ 7.

Therefore, the equation written by the student is FALSE.

You multiply 1.25 by 4 because each brother bought a bag of chips. Then you subtract that by the total and get $13.20 you divide that by 8 hot dog because each brother got 2 hot dogs. By dividing 8 by the  left over amount from subtracting the chips you get how much each hot dog is worth.

Answer:

The number line that shows x > 8

Step-by-step explanation:

First, subtract 15 from both sides

15 + 2x -15 > 31

2x > 16

Then divide both sides by 2

2x ÷ 2 > 16 ÷ 2

x > 8

The answer is:

x > 8

Work/explanation:

To solve this inequality, we need to isolate x.

So first, I subtract 15 on each side:

[tex]\sf{2x > 31-15}[/tex]

[tex]\sf{2x > 16}[/tex]

Now, divide each side by 2:

[tex]\sf{x > 8}[/tex]

Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

Bankruptcy is a legal proceeding involving a person or business that is unable to repay its outstanding debts.

Had Lewis not filed bankruptcy, he would have paid = 90+50+65+75

He would have paid (let us say amount A)= $280

After filing for bankruptcy he has to pay = 205+75+150+110

He has to pay (let us say amount B)= $540

Difference between amount A and amount B = $540-$280

Difference between amount A and amount B = $260

Therefore, Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

A number line is a representation of a graded straight line. The value that is farthest from 2 is √2.1.

A number line is a representation of a graded straight line that serves as an abstraction for real numbers, which are indicated by the symbol 'R'. A real number is considered to correspond to every point on a number line, and a point to every real number.

On the number line, positive numbers are on the right side of the number line while negative numbers are on the left side of the number line. Now, the value of all the given options can be written as,

[tex]\sqrt{2.1}=1.45 \\\\\sqrt{2.4}=1.55\\\\\sqrt{2.5}=1.58\\\\\sqrt{2.9}=1.7[/tex]

The slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is the equation of the line as 5x - 2y = 20.

We have the equation of the line as -

5x - 2y = 20

2y = 5x - 20

y = (5/2)x - 10

[m] = 5/2

Therefore, the slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

The gas mileage of the trucks is the number of miles traveled per gallon of gas

The truck that has the best gas mileage is (b) Truck A, because for every gallon the truck goes 19 miles.

As stated above, gas mileage measures the miles traveled by one gallon of gas.

This means that options (a) and (c) cannot be true, because these options measure the number of gallons used per mile

From the complete question, truck A uses 1 gallon for 19 miles, while truck B uses 1 gallon for 18 miles.

19 miles per gallon is greater than 19 miles per gallon

This means that truck A has the greater mileage

Answer:

B(x=4,x=5)

Step-by-step explanation:

Here,

[tex]x^{2} -9x+20=0[/tex]

We can find the value of x by various methods.

Method 1

By using formula

x=-b±√b²-4ac/2a

For ax²+bx+c=0

Here,

a=1, b=9, c=20

Putting the values.

x=-b±√b²-4ac/2a

x=-(-9)±√9²-4×1×20/2×1

Taking positive one.

[tex]x=\frac{-(-9)+ \sqrt{81-80} }{2} \\\\x=\frac{9+1}{2} \\\\x=5[/tex]

Taking negative one.

[tex]x=\frac{-(-9)- \sqrt{81-80} }{2} \\\\x=\frac{9-1}{2} \\\\x=4[/tex]

x=5,x=4

Method 2

[tex]\hookrightarrow x^{2} -9x+20=0\\\\\hookrightarrow x^{2}-4x-5x+20=0\\\\\hookrightarrow x(x-4)-5(x-4)=0\\\\\hookrightarrow (x-5)(x-4)=0[/tex]
